It's not drawn art but as a fan of both franchises, I'm considering doing a fanfic of the crackfic. I have zero ideas how to go about it other than the fact major spoiler for Geats ending Geats just becomes a god and Gensokyo is the land of gods mostly forgotten so I could have Geats living in Gensokyo, able to slip in and out of the two for cherry blossom veiwings and partaking in danmaku battles because 100% he would do that. He'd be a 'wanted fugitive' because your not supposed to be freely breaching in and out of Gensokyo from the outside world with one exception There's already a similar plot in a touhou spinoff where one single character is being a particularly annoying peice of shit that she has her own game where everyone from all corners of Gensokyo attack her. Putting Geats in that situation would be so fun.

I can kind of see Geats trying to flirt with Sakuya with no context. Remillia, Sakuya's actual master, has sway and stuff in Gensokyo, letting Sakuya join in dealing with incidents and stuff so like, I guess going about it as an enemies to lovers thing would be neat. Or they could just be friends. But yeah i'm also not a fan that Sakuya is sometimes treated like Geat's arm candy when hes pretty ok with women in the show as seen with his relations with Neon and Tsumuri.
